Acupuncture: a new method to treat tic disorders in children

Tic disorders are neurological conditions that affect children and can significantly impact their quality of life. Characterized by involuntary, sudden, and repetitive movements or sounds, these disorders were first described by the French neurologist Gilles de la Tourette in 1885. They currently affect approximately 0.3% to 1% of the world population and are three to four times more common in boys. The problem extends beyond physical symptoms, as children frequently face misunderstanding and social stigma, which also affects their emotional and psychological health.

Conventional treatment of tic disorders presents considerable challenges. The medications traditionally used, such as clonidine, risperidone, tiapride, and haloperidol, can cause significant side effects and require good patient cooperation, which can be difficult for younger children. Behavioral therapies and deep brain stimulation are also options, but each has its own limitations. Faced with these difficulties, researchers have investigated therapeutic alternatives, with acupuncture among the most promising.

In traditional Chinese medicine, these disorders are classified as chronic inflammatory convulsions, and acupuncture has shown good efficacy in relieving spasticity with few adverse effects.

This study reviewed the existing scientific literature on the use of acupuncture for the treatment of tic disorders in children, analyzing both clinical research and experimental animal studies. The researchers examined different acupuncture modalities, including traditional Chinese acupuncture, electroacupuncture, scalp acupuncture, and auricular acupuncture. The aim was to assess the efficacy of these treatments, understand the mechanisms of action, and compare results with conventional drug therapies. The methodology involved analysis of studies that used standardized scales such as the Yale Global Tic Severity Scale (YGTSS) to measure symptom improvement.

The research findings are encouraging and reveal that acupuncture may be an effective alternative for the treatment of tic disorders. Clinical studies showed that acupuncture, when used alone, may be more effective than medications such as haloperidol, tiapride, and aripiprazole, with fewer side effects. When combined with medications, acupuncture enhances treatment benefits and reduces the incidence and severity of medication-related adverse effects. A particularly interesting aspect is that the therapeutic effects of acupuncture appear to be more durable, with a lower relapse rate during follow-up periods of six weeks to six months.

Mechanistically, research suggests that acupuncture acts by regulating brain neurotransmitters, including dopamine, norepinephrine, serotonin, and gamma-aminobutyric acid (GABA), substances fundamental to movement control that are altered in tic disorders.

For patients and clinicians, these findings offer important perspectives for the treatment of tic disorders. Acupuncture presents itself as an especially valuable option for children who do not respond well to conventional medications or who experience significant side effects. For mild cases of tic disorder, especially those diagnosed early, acupuncture may be used as the primary treatment, providing symptom relief and reducing anxiety for both the child and the parents. In more severe cases such as Tourette syndrome, combining acupuncture with medications may maximize therapeutic benefits.

The flexibility of acupuncture treatment, which allows adjustments in session timing and frequency, makes it particularly well suited to the pediatric setting.

It is important to acknowledge the limitations of this research area. Most studies did not include placebo control groups, which raises questions about whether part of the observed improvement could be due to the natural remission of symptoms that occurs in some cases of tic disorders. In addition, ethical considerations make it difficult to conduct placebo-controlled studies in this population. Research on the mechanisms of action of acupuncture is still in early stages, focusing mainly on effects on neurotransmitters but not fully exploring how the technique influences the nervous and immune systems.

Regarding safety, although acupuncture is generally well tolerated, minor complications such as bleeding or bruising may occur, requiring experienced practitioners familiar with pediatric anatomy. More multicenter studies with larger samples are needed to establish more precise treatment protocols and definitively validate the efficacy of acupuncture for tic disorders in children.
